# iroh-http-core

Rust core for [iroh-http](https://github.com/momics/iroh-http) — peer-to-peer HTTP over [Iroh](https://iroh.computer) QUIC transport.

This crate provides the transport layer: an Iroh endpoint, `fetch()` for outgoing requests, and `serve()` for incoming requests. It speaks HTTP/1.1 framing over QUIC bidirectional streams. Nodes are addressed by Ed25519 public key — no DNS, no TLS certificates.

> **Note:** This is a low-level FFI-bridge crate. If you are building an application, you probably want one of the higher-level adapters instead:
> - **Node.js** → [`@momics/iroh-http-node`](https://www.npmjs.com/package/@momics/iroh-http-node)
> - **Deno** → [`@momics/iroh-http-deno`](https://jsr.io/@momics/iroh-http-deno)
> - **Tauri** → [`@momics/iroh-http-tauri`](https://www.npmjs.com/package/@momics/iroh-http-tauri)

## Usage

```rust
use iroh_http_core::{
    IrohEndpoint, NodeOptions, ServeOptions,
    fetch, serve, respond,
};

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    // Bind a local endpoint
    let endpoint = IrohEndpoint::bind(NodeOptions::default()).await?;
    println!("Node ID: {}", endpoint.node_id());

    // Serve incoming requests
    let _handle = serve(endpoint.clone(), ServeOptions::default(), |req| {
        respond(req.req_handle, 200, vec![], None);
    });

    // Fetch from a remote peer (raw FFI-level API)
    let resp = fetch(
        &endpoint,
        remote_node_id,
        "httpi://peer.local/api",
        "GET",
        &[],
        None, None, None, None,
    ).await?;

    Ok(())
}
```

## Features

- **Connection reuse** — QUIC connections to the same peer are pooled and multiplexed
- **Streaming bodies** — request and response bodies stream through `mpsc` channels with configurable backpressure
- **Fetch cancellation** — abort in-flight requests via cancellation tokens
- **Bidirectional streams** — full-duplex streaming via QUIC bidi streams
- **Trailer support** — HTTP/1.1 chunked trailers for streaming metadata
- **Configurable** — idle timeout, concurrency limits, channel capacity, chunk sizes
- **Optional compression** — zstd request/response compression via the `compression` feature (enabled by default)
